Summary on Grant Application Form |
|
Siponic roof drainage differs from conventional designs, BSI 6367, due to the expectation of flow full bore, thus increasing discharge, reducing the diameter of internal pipe networks ad removing pipe gradients. Establishing full bore flow depends on system design and storm characteristics and, due to the necessity to evaluate air from the network, may involve a range of concurrent network flow regimes, from initial free surface, through intermittent full bore and two phase, as the storm intensity grows, to full bore flow. Current design methods assume steady homogenous, full bore flow and cannot predict these interacting unsteady regimes. The applicants EPSRC research modelling building drainage unsteady flow via the method of characteristics moc, forms the basis for a proposed simulation of these regimes that would track their interfaces, include the waterhammer and possible column separation that accompanies sub-atmospheric flow and be compatible with their earlier work. System boundary conditions would be experimentally developed and incorporated into a moc computer model. The work is relevant as it addresses the avoidance of severe damage and loss due tot inaccurate system design and is novel as it provides a computer simulation accessible by system designers, component manufactures and code bodies.
